What Maryland homeowners say

⭐⭐⭐⭐⭐ Excellent Service, Professionalism, and Quality Work! I had an excellent experience with Apper Construction! From the very beginning, Leandro was professional, friendly, and attentive. He took the time to answer all my questions, explain the process, and provide clear information about the work and pricing. I contacted them regarding the installation of a roof vent for my bathroom exhaust fan, and I couldn’t be happier with the experience. I also want to recognize the technician who performed the installation. He did an excellent job, worked professionally, and made sure everything was properly completed. I truly appreciate his attention to detail and the quality of his work. What stood out to me the most was the excellent communication, honesty, professionalism, and dedication to customer satisfaction from start to finish. Thank you to Leandro and the technician for making this such a positive experience. I highly recommend Apper Construction to anyone looking for reliable service, quality workmanship, and a team that truly cares about its customers. I would definitely hire them again!

We were in need of a new roof and there was a time limit on it due to a horrible insurance company, you know the one that’s “on your side”, but they’re really not. I had at least four roofing companies come out and give me their speech like they do. For the fifth company, I dialed the wrong number that day and somehow by the grace of God a gentleman answered by the name of Leandro who owned a roofing and construction company. What are the chances? I Explained my situation and he came out the very same day to check out the roof which was 4,400 sq.ft. Mr. Leandro was so professional and answered all of our questions. Just listening to him speak about the procedure for a roof replacement was remarkable. Needless to say, he and his employees got the job! My roof was replaced even with new plywood, in one full working day. Mr. Leandro brought nine workers starting 7 AM and leaving around 6 PM. Once the Job was complete, you would’ve never known they had been there, which was so impressive. They had tarped everything, blew gutters out, and used a huge magnet to make sure there were no loose nails laying around. Throughout this whole ordeal, did I mention the price was very very fair! God Bless You Mr. Leandro and your hard-working employees!

From first meeting until job completion Apper was responsive, punctual, and expertly professional: highly recommended for vinyl siding replacement. The company owner showed personal interest by doing the initial estimate, checking work progress, and asking my impressions as work progressed. The 5-man crew operated efficiently, with well orchestrated precision, completing the job with excellent results in 2-days. Apper Construction is the place to start for expert vinyl siding replacement at a fair price!

Strongly recommend Apper construction for any roof and exterior needs. Noticed a leak on Sunday, they were out on Monday to assess and give a quote. Leandro and his team were impressively thorough and they did a great job. Very thorough cleanup too!

Windows do double duty in Linthicum, and the town's setting is the reason. Sitting right next to BWI airport, much of Linthicum lives under the flight path, so beyond keeping heat in and drafts out, windows are the front line against aircraft noise. The homes across Old Linthicum, Andover, Twin Oaks, and Belle Grove were built between the 1940s and 1970s, and the original single-pane, old aluminum, and early vinyl windows in them do a poor job on both counts — they fog and fail at the seal, rattle in their frames, leak conditioned air, and let jet noise pour straight into the room. It's one of the few places in Anne Arundel County where the sound question comes up on nearly every estimate. We replace with ENERGY STAR-rated windows — double-hung, casement, and bay units with Low-E coatings and argon fill — and for flight-path homes we spec sound-reducing glass packages, including laminated and dissimilar-thickness insulated glass that measurably lowers the noise that comes through the old windows. The energy side matters too: these mid-century Linthicum homes bleed heat and cooling through their aging windows, and swapping to a properly sealed Low-E unit shows up directly on the BGE bill. Which install method we use depends on the opening — an insert replacement where the existing frame and sill are sound, keeping the original trim, or a full-frame rebuild where an old leaking window has softened the frame, so we can take it to the rough opening and inspect for hidden damage. Every window is flashed and foam-sealed to stop drafts and air leakage. Because Linthicum's housing stock is older, openings are rarely perfectly square or a standard modern size, so we measure every window individually rather than order off a rough count — a window ordered a quarter-inch off is a window that whistles and leaks for twenty years. Every job is installed by our own local crew with a written, line-itemed estimate that spells out the exact product, glass and sound package, and install method. We pull Anne Arundel County permits where required and haul off every old sash and frame before we leave. As a licensed window contractor in Linthicum, we handle full-frame window installation and replacement.

Most Linthicum window projects run about $650–$1,500 per window installed, or roughly $9,000–$34,000 whole-home, depending on window type, glass package, insert vs. full-frame, and any frame rot. Sound-reducing laminated glass for flight-path homes sits at the higher end. You get a written, line-itemed estimate before anything is scheduled. Call 410-508-6141.

Windows in Linthicum — Common Questions

How much does window replacement cost in Linthicum, MD?

Most Linthicum window projects run about $650 to $1,500 per window installed, or roughly $9,000 to $34,000 whole-home. Glass package, insert vs. full-frame, and any frame rot drive the number, and sound-reducing laminated glass for flight-path homes sits at the higher end. You get a line-itemed written estimate first.

Can new windows cut the BWI airport noise?

Yes, meaningfully. For flight-path homes we spec sound-reducing glass — laminated and dissimilar-thickness insulated units that measurably lower aircraft noise compared with the old single-pane and aluminum windows in most Linthicum homes. We'll recommend the right package for how much noise you're dealing with.

Why are my old windows foggy between the panes?

That fogging is a failed seal — the gas between the panes leaked out and moisture got in, so the glass no longer insulates. It's common on the aluminum and early vinyl windows in Linthicum's mid-century homes. New Low-E, argon-filled units restore the insulation and clear the view.

Insert or full-frame replacement?

It depends on the frame. If the existing frame and sill are sound, an insert keeps your trim and installs cleanly. On older Linthicum homes where a leaking window has softened the frame, we recommend full-frame so we can inspect the opening and rebuild it right.
